There are some building blocks (like reduction to Hessenberg and Schur) making it possible to solve this problem in ScaLAPACK. But at the same time, there is no driver. It...

This is a gap in ScaLAPACK API.

This is a gap in ScaLAPACK API: it makes using P?GEBAL routine problematic.

This is a gap in ScaLAPACK API: it makes problematic to compute the eigenvalues of a real unsymmetrical matrix.

This is a gap in ScaLAPACK API. The link below shows that HSEQR performs much faster than LAHQR. It means that ScaLAPACK implements an inefficient algorithm for complex matrices. http://netlib.org/scalapack/scalapack-2.0.0.html
